GUDGEON-ROLLER.

SPECTFICATION forming part of Letters Patent No. 283,551, dated August 21, 1883. Application filed June '16, 1883. (No model.)

chinery; also inpaper machinery; and the invention consists of a new form of gudgeon, and of the combination therewith of a surrounding bushing forced into the end of the wooden roller, whereby the gudgeon is held with great firmness and security and prevented from working loose in the end of the roller. r p I Reference is to be had to the accompanying drawings, forming part of this specification,

'in which similar letters of reference indicate corresponding parts in allthe figures.

Figure 1 is a sectional elevation of a gudgoon-roller made in accordance with my invention. Fig. 2 is an end elevation of the same. Fig. 3 shows the gudgeon, bushing, and roller detached; and Fig. 4 is a sectional elevation of the gudgeon, taken on the line x x of Fig. 3. i

A represents the wooden roller B, the gudgeon, and C the bushing, which is, by preference, of the same construction as the bushing shown and described in my Patent 170. 267,817, dated November 21, 18S2-that is, formed with the central portion, a, surrounding ring b, and radial eonnect-ing-pinsc, the central portion having the square or angular passage d made'through it, as shown in Fig. 3. Y

The gudgeon B is formed with the round journal part cand square portion j. Beyond this square portion it might be made solid; but I prefer to form it with the blades four in numben-which facilitate the entrance of the gudgeon into the end of the wooden roller, andwhich also prevent the gudgeon from turning in the roller.

The square portion f fits in the angular passage d of the bushing 0 when the parts of the roller are assembled, and in practice will be made slightly tapering and a trifle larger than the said passage, so that when the gudgeon is forced into the end of theroller Athrough the bushing the central portion of the bushing will be slightly expanded, causing the bushing to take a firm grasp upon the gudgeon.

The roller A is bored at its ends, as shown at 71, forreceiving the central portion, a, of the bushing G, and has the circular lterf'i formed in it around the bore h, for receiving the circular ring b,- and the lcerf'iand bore 11 are, by-

preference, made deeper than the width of the ring D and central portion, a, of the bushing, so that when the parts are put together the bushing may be pressed in beyond the surface of the end of the roller, as shown in Fig. 1, thus giving the end of the roller an all-wood surface.

In putting the parts together the bushing G is first pressed into place in the ends of the roller A, and then the gudgeon B is passed throughthe passage (1 of the bushing, andthen settled into the wood to the position shown in Fig. 1. In this manner the bushing holds the gudgeon with great firmness, and the ring I) of the bushing,surrounding the portionsj of the roller, strengthens the roller at the ends, and

' makes the roller, as awhole, strong and durabio.

I do not abandon or dedicate to the public any patentable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this application or in other applications for Letters Patout that I may make.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the gudgeon B, having square portion j, of thebushing G, having central portion, a, and surrounding ring I), substantially as described.

2. he gudgeon B, having square portion f, made slightly tapering, in combination with the bushing having the passage d, substantially as and for the purposes herein described.
